We have measured TV audience in the Czech Republic since April 29, 2002, when we first started with the 5-year TV audience measurement project for the Association of Television Organizations.

Parameters of current TV measurement in Czech Republic 2018-2022

Measurement is carried out on a representative sample (panel) of 1,900 households with TV sets (ca. 4,450 individuals). Households participating in the measurement have guaranteed anonymity in relation to our clients and data users.

The audience is measured for every TV set in each household, and all members of the household that are over 4 years old participate in the measurement.

We guarantee the daily supply of data from at least 1,700 households.

The panel of households was based on an extensive Establishment Survey conducted in 2017, with the goal of defining the basic characteristics of the TV audience.

The panel of households is regularly updated. 25% of the panel is replaced every year.

The structure of the panel is regularly checked and modified, so that the sample of households matches the socio-demographic profile of households and individuals in the Czech Republic) according to the current data of the Czech Statistical Office (CZSO).

The panel composition is regularly checked with regard to possible changes in characteristics that affect the TV audience in the Czech Republic.

The behaviour of panel members is checked daily by Nielsen Admosphere.

Monitoring of changes in the TV population is provided by a “Continual Survey,” which is carried out on a quarterly basis on a representative sample of at least 12,000 households yearly.

The Continual Survey for example examines the TV behaviour of Czech households, their TV set equipment, TV channel reception etc.

We measure TV audience in households using a TV-meter system. Audiomatching is the dominant technology in the measurement – a comparison of sound prints from all measured TV sets with a reference set of sounds of the measured TV channels. The measurement does not depend on the means of TV signal reception (DVB-T, satellite, cable, IPTV, Internet).

Since 2013, the time-shifted audience of programmes has been included in the measurement project, i.e. the audience of a programme after its TV broadcast time, over a horizon of 7 days. It can occur on TVs with hard drives or other device allowing the recording and playback of TV broadcasts, or with help of so-called Smart TVs etc.

For the digital part of the project (PEM D) we use site-centric technology, which works on the principle of measuring scripts (Nielsen SDK) implemented directly in video players on websites and in mobile as well as HbbTV applications of connected TV operators.

The data collected from the panel are checked every morning by Nielsen Admosphere and combined with information about broadcasted programmes from broadcasting protocols supplied by different TV channels.

Daily data are available every morning by 8:00 am, within 2 hours of the end of the previous TV day, which lasts from 6:00 a.m. to 6:00 a.m., including Saturdays, Sundays and all national holidays.

The supplied data contain information about TV audiences accurate to the second, information about programmes, and socio-demographic information about households and the individuals living in them.

The data from the digital measurement part (PEM D) is delivered daily for the previous day, no later than by 12:00. Above the possibility of separate PEM D data analysis, the PEM TV and PEM D Data Harmonization Module can analyze data from both parts of the measurement together in one software.

Information about individual respondents is continuously enriched with information about their lifestyle and consumer behaviour from the Lifestyle Survey (LSS).
